DGOR-HANGER.

Specification of Letters Patent.

Patented June 24, 1913.

To all whom it may concern:

Be it known that I, WVILLIAM H. FITCH, citizen of the United States, residing at Aurora, in the county of'Kane and State of Illinois, have invented certain new and useful Improvements in Door Hangers, of which the following is a specification.

This invention relates to improvements in door hangers of the type popularly known as trolley hangers in which two pairs of wheels are mounted tandem on a frame and which supports the.pendant members connected with the door.

The especial object of the improvements embodied in this application for patent is to provide a hanger of the type mentioned which will facilitate the vertical adjustment of the door.

A further object is to provide a construction which will retain the several members making up the complete device in their adjusted relations without danger of their working loose by getting out of adjustment.

A still further object is to provide a construction in which the use of cast iron members may be avoided and certain economies of construction conserved by the use of standard bolts, nuts, and metal stampings of simple form.

In the accompanying drawing I have illustrated my invention in approved form in the following views Figure 1 shows the complete hanger in side elevation with a method of attachment to a door indicated; Fig. 2 is a view in vertical section taken on substantially a, median line through Fig. 1.

Referring to the details of the drawing, 3 represent the trolley wheels which are arranged in pairs and mounted on axles or journals 4, which are carried near the ends of the truck which is made up of two flat vertically arranged metal straps 5. At their mid-lengths these straps are expanded outwardly so as to provide an opening or way for a bolt 6 which extends upwardly from its head 6 through said opening. The expanded portions of the straps 5 have a rectangular opening 5 out therein about m1dway between the upper and lower edges of the straps, said opening being of suflicient size to receive a nut 7 which is inserted therein and is threaded to receive the bolt 6 the nut being held against rotation by the surrounding edges of said openings. The

bolt also carries a lock nut 8 which is arranged below the lower edge of the truck plates 5. Between the lock nut 8 and the head 6 of the bolt is inserted a link 9 made of a strap of flat metal with a central opening' to receive the bolt 6 and with its end portions bent downwardly and preferably to receive loosely a non-threaded bolt 10 which is supplied with the usual head 10 and has a cotter pin 10 in its opposite end to hold the bolt against displacement. Hung from the bolt 10 is a second link 11 made of strap metal the end portions 11 of which are perforated to receive the bolt 10, and below said portions the strap is bent outwardly as at 11 and then inwardly to form the horizontal portion which is arranged below the door-engaging plates 12 and 13 when the parts are assembled. The plate 12 is formed with a vertical portion which is bolted to the door and with a horizontal portion which is slotted transversely as at 12 and said portion overlies the corresponding angular plate 13 with its transverse slot 13*. The link 11 extends under the horizontal portion of the plate 13 and is perforated at its center to receive the bolt 14 which extends upwardly through said link and through the slots 13 and 12 and on its threaded stem, carries a nut 14 which when screwed down impinges upon the walls of the plate 12 adj acent the slot 12* and thus serves to clamp the link 11 and the plates 12 and 13 together. Upon loosening the nut 14, the hanger may be adjusted laterally relative to the door 15 or the latter may be adjusted relatively to the hanger as may be desired to meet the existing conditions.

Upon removing the cotter pin 10, the bolt 10 may be withdrawn and thus the links 9 and 11 disconnected from each other so that the door may be removed or disconnected from the upper part of the hanger without disturbing the latter. By loosening the lock nut 8 on the bolt 6, the latter may be turned by applying a suitable wrench to its head 6 and thereby adjust the strap 9 relative to the truck thus increasing or diminishing the distance between the door and the truck.

It will be obvious that the members 5, 9, 11, and 12 are all adapted to be produced from rock iron strap or sheet metal with simple punch and die press operations, thereby securing economy in the manufacture of the article which is highly desirable and at the same time producing a device that will be stronger and more durable than if made of cast iron.

From the construction described it will be noted that any movement of the door in the direction lateral to its sliding movement on a track will be confined to the pivotal connection between the two links 9 and 11. It will also be noted that the plates 12 and 13 are not weakened by cutting slots therein to receive the member 11, a construction shown in United States Patent No. 845,989 of March 15, 1907, and that by extending the link 11 the entire width of the plates 12 and 13, I obtain the advantage of the maximum bearing for said plates.

Having thus described my invention what I claim is 1. In a door hanger, the combination of a wheel carrying truck composed of metal Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents,

straps bent to provide a bolt way therebetween, a bolt adjustably mounted in said way, links pendant from said bolt and pivotally connected together, and door plates connected with said links.

2. In a door hanger, a wheel carrying truck composed of parallel metal plates arranged edgewise, expanded at their midlengths to provide a bolt way and slotted in said expanded portions, a nut non-rotatably arranged in said slot, a bolt mounted in said way and engaged by said nut, door supporting members connected-with said bolt, and means for locking said bolt against rotation relative to said door-supporting members.

In testimony whereof I afiix my signature 7 in the presence of two witnesses.
